There may be better and more knowledgeable replies, but I understand this as 'the beat goes on.' That is, the drums continue to keep the expected rhythm on the song in a constant manner, with the music intermittently changing slightly ahead of the beat. So, in that sense, the drums are never pulled.

Try it. I've found it sounds good to me when used in a repeated pattern on something like beat one or three of bar two and four in a pop song. A little goes a long ways.

Help! I've fallen up and can't get down!
